AWS CloudFormation now offers the feature of Stack Refactoring that lets you move resources between stacks.
Stack refactoring is useful when you want to split a large monolithic stack into smaller, more manageable stacks; reorganize resources to better align with your application architecture or organizational structure; or rename the logical IDs of resources to make templates more readable.
In this example provided in the post, you can create a stack having an SNS topic with a lambda function subscribed to it.
You can then move the SNS subscription to a new stack. The entire process is covered in detail in the article.
To split a monolithic stack into smaller, focused stacks while using exports and imports to maintain dependencies between stacks is demonstrated in the post.
Stack refactoring is valuable for teams looking to improve their infrastructure maintainability and align their resource organization with evolving architectural patterns.
Remember to thoroughly test your refactoring plans in a non-production environment first and always ensure that your new stack structure maintains necessary security and access controls.
Stack refactoring eliminates the traditional need to remove the resource and then import the resource when restructuring stacks, thereby reducing misconfiguration risks and saving time.
Stack refactoring IT professionals the flexibility to manage and reorganize their CloudFormation stack while functioning effectively under a changing environment.
The process of stack refactoring enables more disciplined organization and resource utilization.
